Blink (Su): A blinking spirit can blink as the spell cast by an 8th-level sorcerer, and can evoke or end the effect as a free action.

Dimension Door (Su): A blinking spirit can teleport as dimension door cast by an 8th-level sorcerer, once per round as a free action. The ability affects only the blinking spirit, which never appears within a solid object and can act immediately after teleporting.

Light (Ex): The blinking spirit's head generates light as a permanent light spell (20 ft radius). As an extraordinary ability this light can not be dispelled, and will not be supressed in an antimagic field. It will be negated by darkness and similar spells, however.

Light ray (Ex): The blinking spirit attacks by focusing light. The attack is a ranged touch attack, dealing 1d8 damage. It has a range of 120 feet. The blinking spirit may choose to blind the opponent instead of hurting him. If so, the target must succeed at a Fortitude save (DC 18), or be blinded for 2d4 rounds.

A blinded creature suffers a 50% miss chance in combat (all opponents have full concealment), loses any Dexterity bonus to AC, grants a +2 bonus to attackers' attack rolls (they are effectively invisible), moves at half speed, and suffers a -4 penalty on most Strength- and Dexterity-based skills.
